Question

complete the following table​

Answer 1

this is the answer of height and area of triangle

Answer 2

Answer:

1) area of triangle = 1/2 b×h

257.20= 1/2 ×20.75 ×h

257.20×2 /20.75 =h

h= 24.79 cm

2) area of triangle =1/2×b×h

1/2× 640× 225= 72000cm^2

3) area of triangle = 1/2×b×h

494 = 1/2 ×38× h

h= 26 cm

4) area of triangle = 1/2bh

285 = 1/2 ×15 ×h

h = 38 cm
